WEAR COMPENSATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 395,275, dated December 25, 1888. Application filed March 23, 1888. Serial No. 268,227. (No model.)

To all whom it may concern.-

Be it known that I, ELWIN R. HYDE, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in ear-Compensating Devices for Grinding and other Machines, of which the following is a specification.

This invention relates to improvements in devices for taking up the wear between the ends of journal-bearin and the ends or hubs of a pulley or pulleys or other wheel on a shaft or arbor supported in said bearings, whereby there will be no endwise movement of the said pulley or wheel or of the shaft to which the same is secured; and it consists in the construction and combination of parts, all substantially as will hereinafter more fully appear.

In the accompanying drawing, the present invention is illustrated as employed in connection with a lnii'fc-griiuling machine, the figure being a partial elevation and a longitudinal vertical section thereof.

In the drawing, A A represent standards carrying the journal-boxes l3 13, in which bears the arbor or shaft 0, having thereon between said bearing-boxes the hubbed speedpulley D, and at each end carrying an emery or other suitable grimling-wheel, G, as shown. Between said journal-bearings l; l; and the ends of the hubs a of the pulley are interposed loose collars Z) I). l leaded screws f f are entered longitudinally into screw-threaded sockets inthe ends of the hub of the pulley, and in a manner to be turned outwardly there from to bear against the said collars Z2 Z) to force them outwardly and maintain them l against the ends of the said journal-bearings.

On the wearing away of the ends of the screws, the journalsbearings, or the collars, to such an extent that the arbor would have any endwise play in its bearings, the said screws are turned outwardly to force the collars b b closely against the journal-bearings.

The ends of each of the journal-boxes B B are provided with annular ribs or flanges g g, and the collars b b, also the collars b b outside of and between said journal-bearings and the grinding-wheels, have within their ends recesses or depressions m m, surrounded by the annular walls 7?, which annular walls overlie the said annular flanges of the journal-bearings, thereby preventing the entrance of dirt, etc, into the said bearin \V hat I claim as my invention is-- l. The combination, with the ournal-hea ings l3 13, of an arbor having the pulley provided with the screws f, and the loose collars I) Z) between said screws and jmirnal-bearings, substantially as described.

2. The combination, with the journal-bearings B 13, having on their ends the annular flanges g g, of the arbor having thereon be tween said bearings the pulley provided with the screws f, the loose collars Z) Z) between said screws and the inner ends of said jourrial-bearings, the wheels on the end portions of said arbor, and the collars b 1) between said wheels and the outer end of said journalbearings, the said collars Z) Z) b I) being provided with the depressions m, all substantiall y as and for the purpose described.
